The Technical Distinction That Can Mean Everything in a Claim
A commercial umbrella policy sits above your GL, commercial auto, and employers liability policies — extending your total liability protection beyond what any single policy can provide. For contractors facing large projects, high-value claims, and contract requirements, umbrella coverage is essential.
Follow-Form: The Excess Liability Approach
A follow-form umbrella (functionally an excess liability policy) uses the exact same terms, conditions, and exclusions as the underlying policy it sits above. It extends the limit only — it doesn’t add new coverage. If the GL excludes something, the follow-form umbrella excludes it too.
Drop-Down: True Umbrella Coverage
A true umbrella with drop-down coverage steps in to provide direct coverage for claims that fall in gaps between underlying policies or that underlying policies exclude — subject to a self-insured retention (SIR). The umbrella becomes the primary insurer for those claims.
When Drop-Down Matters
Drop-down activates in scenarios like: a claim excluded by GL but not specifically excluded by the umbrella; a claim that falls between coverage lines with no underlying policy; or when an underlying carrier becomes insolvent. In these situations, the drop-down umbrella provides protection that pure excess liability would not.
The Self-Insured Retention (SIR)
When drop-down activates (no underlying policy), the SIR is the amount you pay before the umbrella begins. SIRs typically range from $10,000 to $100,000. The SIR exists because no underlying policy’s deductible applies — you provide the ‘first dollar’ equivalent.
Which to Buy
For most contractors, follow-form/excess liability satisfies contract requirements and provides adequate protection. True umbrella with drop-down is worth the additional premium if you have complex operations with potential coverage gaps between policies, or if your contracts specifically require a true umbrella form.
